Gematria

One of the rabbinic hermeneutic rules for interpreting the OT. It consisted of explaining a word or group of words according to the numerical value of the letters or by substituting and rearranging certain letters according to a set system. By that rule of interpretation, for example, some rabbis have argued that Eliezer (Gn 15:2) was worth all the servants of Abraham put together, for Abraham had 318 servants and Eliezer’s name equaled 318 (Gn 14:14). The name Babylon is arrived at in Jeremiah 25:26 and 51:41 by substituting the last letter of the Hebrew word for the first letter of the same word.

The pseudepigraphal Epistle of Barnabas interprets the 318 servants of Abraham (Gn 14:14) as pointing to Jesus’ death on the cross, because 300 is the numerical value of the Greek letter “t,” which is cross-shaped, and 18 the value of the first two letters of the Greek word for Jesus. In the book of Revelation the number of the beast is 666 (Rv 13:18). If the number seven is considered to be the perfect number in the Bible, and if three sevens represent complete perfection, then the number 666 falls completely short of perfection.
